16 * merge_keys - Takes 2 public keys and merges them.
17 * @a: The old key. The merged key is returned in this structure.
18 * @b: The new key. The changed from old to new keys are returned in this
21 * This function takes 2 keys and merges them. It then returns the merged
22 * key in a and the difference between this new key and the original a
23 * in b (ie newb contains the minimum amount of detail necessary to
24 * convert olda to newa). The intention is that olda is provided from
25 * internal storage and oldb from the remote user. newa is then stored in
26 * internal storage and newb is sent to all our keysync peers.
28 int merge_keys(struct openpgp_publickey *a, struct openpgp_publickey *b);
31 * update_keys - Takes a list of public keys and updates them in the DB.
32 * @keys: The keys to update in the DB.
34 * Takes a list of keys and adds them to the database, merging them with
35 * the key in the database if it's already present there. The key list is
36 * update to contain the minimum set of updates required to get from what
37 * we had before to what we have now (ie the set of data that was added to
38 * the DB). Returns the number of entirely new keys added.
40 int update_keys(struct openpgp_publickey **keys);
43 * get_signed_packet - Gets a signed packet from a list.
44 * @packet_list: The list of packets to look in.
45 * @packet: The packet to look for.
47 * Walks through the signedpacket_list looking for the supplied packet and
48 * returns it if found. Otherwise returns NULL.
50 struct openpgp_signedpacket_list *find_signed_packet(
51 struct openpgp_signedpacket_list *packet_list,
52 struct openpgp_packet *packet);
55 * merge_packet_sigs - Takes 2 signed packets and merges their sigs.
56 * @old: The old signed packet.
57 * @new: The new signed packet.
59 * Takes 2 signed packet list structures and the sigs of the packets on
60 * the head of these structures. These packets must both be the same and
61 * the fully merged structure is returned in old and the minimal
62 * difference to get from old to new in new.
